My second child (Decimo)

looks like thrips my friend. Look underneath the leaf for tiny black spots. The tiny fuckers suck the sap(or plant liquids dont know exactly what they suck haha) then the little marks you see are damaged leaf. The underside of the leaf will have little black spots which is their poo. Can get a pesticide which is recommended for use with marijuana plants. We also use predator mites to stop pests in the grow room Happy growing pal
